Default 289 runs like crap

https://www.youtube.com/watch?v=SDrD...e_gdata_player

Everything is new, I've adjusted the rockers by the book 4 or 5 times. I originally had stock rockers upgraded to roller to tipped rockers and had to replace the pushrods because when the engine was put back together my buddy "torqued" the rockers and bent my old pushrods. The engine just seems to be running rough and I'm not sure what to do. ....

Any thoughts?

The video is on private.. and why are you trying to start the engine with the valve cover off.. It's going to shoot oil.. lol.. without any more details I can't really say.. does the exaust smoke? do you smell anything funny at idle? does it make power? are you overheating? does the roughness go away past 1200RPM? need more details

stock 289. Holly 650, spec less mild cam, In the pic I was adjusting the rockers..... and it didn't make since to me why oil would only be shooting or of cyl 1 as opposed to them all.. video should be fixed

No smoke out exhaust no unordinary smells I guess it sounds better when in gear? But pretty much just sounds the same through all rpm ranges. And Im scared to drive it very much in fear of damaging somthing...

If you changed nothing else but the rockers (and then the pushrods) I'd say it more or less has to be a valve problem. If you are certain that the rockers are adjusted properly then you have other problems.

If you managed to bend the pushrods you could have problems with collapsed lifters, bent valve stems or (less likely) damaged cam lobes. The fact that you only have oil squirting from one pushrod would cause me to look at the lifters.

Are the pushrods the correct length? The roller tip needs to be centered on the valve stem.

If you spun the pushrods when tightening, you probably have open valves.

Do this:

Turn the engine so the #1 intake valve is fully opened. Loosen the exhaust valve pushrod up and down (NOT spinning).
Tighten this valve until no up and down movement can be felt, then tighten an additional 3/4 turn.

Turn the engine so the #1 exhaust valve is fully opened. Loosen the intake valve pushrod up and down (NOT spinning).
Tighten this valve until no up and down movement can be felt, then tighten an additional 3/4 turn.

Repeat for the other 7 cylinders.

until you can move the #1 exhaust until you can move the #1 intake
+1 I agree

I am pretty sure you have a bad lifter..It should not be shooting oil out like that.I have seen that happen before when a rocker was adjusted down way too tight.

Ford, and almost every cam manufacturer call for 3/4 turn.

Was it running correct before you started changing things?

when I replaced my pressed in studs with screw in, added roller rockers, etc... I bent every push rod... turned out I needed hardened rods... DOH! rookie move.. I was so excited about getting that thing running, I forgot to replace the rods with hardened steel... also had a few guide plates to replace after that too... all is sweet now...

so.... did you happen to replace your rods with hardened steel?
